Abstract
A system including an ordered data table containing linked lists of MAC addresses has a multiplicity of search engines which have their access to an LRU engine under the control of a token which is passed from one search engine to the next when the LRU engine has completed reordering the table after an address look-up. The system avoids conflicts between searching and reordering and allows reordering to be performed at a controlled rate.
